SIGNAL DEVICE.

lie it known that l. XJicnoLAs E. Hessian.

1a. cilixcn oi the l nited States. and resident of dcrscy ("iii-3 in the county of Hudson and State oi New Jersey, have invented con ,iain new and useful lIHlHOVCIElQIltS in 81% na l Devices, oi which the following a.

' specification.

This invention relates to a. signal device and is paricularlr adapted 'to ihc rear suds of motor vehicles. Tho organization of the invention includes means for energizing the lamp oi the signal device by the operations of the ions hrakc pcdakso that the signal is in plain view whcn the foot brake is set.

in the accompanying. drawings Figiirc 1 represents a plan \ic-W of thc mechanism and frame of a motor car with the invention attached tlicrcl o Fig. 2 shows an enlarged plan view of the elements oi? the invention with a fragmentary portion oi? the inc-tor car, Fig. 2-1- is a iragiiieiiiary right hand side vicw and section on l he line 3. 3 of hi 2. Fig. 4: z-cprcscnts a partial front ricw of Fig. Fig. 5 shows a partial section of Fig. 3 on the line and (3 shows a modification of a. detail.

shown with wheels has er;- insulating insulating 37. An arm 88 on the shai'fi $37 is pinned to the link 39 which lai tcr in burn is pinned to the equalizer bar 40. Pull'rods' ll connect the cqualisz. bar with arms 42 extending; from the rocker shaft lih'and the latter operates the fool; brakes i-l. A pair of collars ll"), l? are-fastened to the rod 83.

A movable collar 48 encircle-s said rod and has formed therewith thefsoe ii). A pin 50 in the larior oollar engages a groore 51 in the rod I A sprii'ig encircles the rod 33 audbears between the collar 47 and-l8. A flexible U shaped contact piece 56 has one and 5'? fastened so the block and the other end is intbe path of theses $29. A stationary con' tact plain (ll is fastened lo the block 32.

From the cross girder fliexicnds a bracket 66 which supports a. signal box. The said Application filed Gctobcr 11, 1918. Serial No. 795317.

box is shown with the roof 67, bottom 68, rear wall 69, hinged front frame 70 with the latch 71 and-end walls 72. The front frame 70 has supported therein preferably a. glass plate 73, which. is painted or covered with anon-transparent material. Lettersl are formed in the paint ornon-transparent material to enable light rays to pass therethrough. A slide 7 5 is guided in lips formed with the hinged front frame.

A source of adjustable illumination, preferably an electric bulb 76. is located in the signal box. The signal box with its bulb and appurtenances I designate a signal.

Asourcc of electric current in this instance electric batteries is shown at from which extend the wires 81, 82, constifiutirig the cable 90. The wire 82 extends toone pole of an electric switch 92 having the handle 93. A wire 94.- extends' from the other pole. of said switch to the contact plate (5.4; A wire J5 extends from the con-- tact piece 6 and with the wire 82forn1's the cable 96. The wires '95 and 81 form the. cable 97 which latter extends to the bulb To. in Fig. 6 the invention is modified by replacing the transparent material 73by an opaque material 100 in which are formed letters by means of small openings 101.

To use the invention the operator-of the motor vehicle bears onthe foot pedal 35 which sets the foot brakes 44 in the ordinary way. The handle 93 of the switch being in its closed position. the flexible contact piece 56 is brought in contact with. the plate 64 which closes the circuit for the electric bulb T6. and energizes the electric ap- Upon the release of the foot pedal 35 the flexible contaca piece 56 separates from the plate (is and bhe electric circuit for the bulb is broken and consequently the illumination in the signal box ceases. It will be observed that ,the foot brakes coact with the illumination in the signal box, so 'tl'iat when the foot brakes are set the signal is in plain View.

The. slide 75 is pulled outas shown in Fi' s. 3 and 6 when the signal is used and closed to prevent injury to the box when said signal is not used. The hinged frame 70 allows the signal box to be opened for the pur ose of cleaning and adjustment of the bulb 26.

Having described my invention What I purbenanccs thereof to obtain illumination in the signal box and bring the letters on she plate 73 clearly into new.
